Brief introduction to the products
Brief introduction to the products
Wind (PV) The special type box-type substation is a special equipment
for boosting 0.69kV voltage to 38.5kV at the exit of the wind
(photovoltaic) power unit, which is a special equipment for our company
to absorb wind power from Europe and America Of the experience, combined
with the domestic wind (PV) power of the situation and the status quo
tailor-made specifically for the wind (PV) power generation of new
products. The box-type variable using wind (photovoltaic), "one into a"
special structure, according to the different ways of high-voltage
outlet, divided into American, European and combined three structural
The product has a set of strong, small footprint, small investment, easy installation and maintenance, handsome in appearance, strong weather and so on. Products with a variety of structures to meet a variety of special use conditions, the use of the transformer capacity specifications, to meet the 5MVA and below the wind (photovoltaic) power generating units supporting. It appears to adapt to the establishment of a wide range of wind (photovoltaic) power plant in the trend, wind (PV) power generation system, the best matching products.
● According to the wind (photovoltaic) electrical technology for special design, with the wind (photovoltaic) electric field "into a" special requirements of the characteristics.
● Split box structure, high pressure chamber, low pressure chamber and transformer constitute a separate unit. The high-voltage outlet unit and the low-voltage incoming line unit are separated from the transformer and are safe and reliable.
● Transformer heat sink directly exposed to the air, heat capacity, to prevent the overheating of the temperature inside the box and make electrical components failure.
● Overload capacity, loss of small, short-circuit ability, strong ability to mine.
● Box made of new materials, and after the anti-corrosion surface treatment, the ability of sea water, salt spray corrosion, and to prevent ultraviolet radiation.
● Small size, simple structure, reasonable layout, transportation, easy installation.
● The product is beautiful and nice, and the surrounding environment can be very good coordination.
■ Wind (PV) electric special box-type substation (US) structure and dimensions
1, the wind (PV) special box-type substation (US) by the high-voltage room, transformer, low-voltage chamber composed of three parts, the use of low-pressure into the high-pressure "one into a way," Transformer high and low voltage wiring pile head Using the level of wall bushing leads way, were arranged in the body of the front and rear ends.
2, the wind (PV) special box-type substation (American) load switch and fuse package in the tank, the load switch operation in the low-pressure room. Fuse main fuse and backup fuses, the main fuse can be charged to repair, backup fuse breaking capacity, can effectively protect the normal operation of the transformer.
3. Low-voltage room with low-voltage frame air switch or low-voltage fuse for receiving wind (PV) motor output 0.69kV voltage, can also be configured according to user needs to provide small capacity transformers box and wind (PV) tower lighting Electricity.
4, the transformer is wind (PV) electric field dedicated step-up transformer, can be equipped with S11, S13 or amorphous alloy and other low-loss transformers.
5, for 3MW, 5MW wind (photovoltaic) motor group, can be directly input voltage of 6.3kV low voltage side of the box changes.
■ wind (PV) special box-type substation (European) structure and dimensions
1, the wind (PV) special box-type substation (European) by the high-pressure room, transformers, low-voltage chamber composed of three parts, using low-pressure into the high-pressure "into a way."
2, the wind (PV) special box-type substation (Continental) high-pressure room selection of the company specifically for the wind (photovoltaic) electric box developed by FZRN-40.5 vacuum load switch, the switch placed in the high-pressure room. The switch is provided with a high-voltage fuse as a knife-fuse isolating switch for the switch. When the knife melt isolating switch is operated, it has obvious breaking point. The switch has a perfect mechanical anti-mis-locking function, the knife melt isolation switch and vacuum interrupter using mechanical linkage, when the vacuum circuit breaker in the closing state, the knife fuse isolation switch can not be divided into operation, when the fuse blown, The vacuum circuit breaker is tripped by the linkage.
3, wind (PV) special box-type substation (European) can be equipped with the requirements of the user and the environment in harmony with the shell, the transformer installed in the shell.
■ wind (PV) electrical special box-type substation (modular) structure and dimensions
1, the wind (PV) special box-type substation (modular) by the high-pressure room, transformer, low-voltage chamber composed of three parts, using low-pressure into the high-pressure "one into a way."
2, wind (PV) special box-type substation (modular) high-pressure chamber vacuum load switch fuse combination and isolation switch with the outlet. Vacuum load switch fuse combination for breaking load current and transformer protection, power maintenance, isolation switch open, with a clear break point to ensure safe operation. Load switch fuse combination and isolation switch between the perfect mechanical locking, safe and reliable operation.
3, wind (PV) special box-type substation (modular) transformer with external structure.
4, Wind (PV) electric special box-type substation (modular) can also be configured for the wind (photovoltaic) box developed FZRN-40.5 vacuum load switch, use this switch, can reduce the pressure chamber depth, Small box variable volume.
